That time I got reincarnated as a slime

After being defeated and humiliated by Milim, the Demon Lord Carrion's follower Phobio is seething. That is perfect for Footman and Tear of the Moderate Harlequin Alliance's plans--they can use Phobio's anger to summon the grand beast Charybdis. Soon Rimuru learns Chardybdis has come to life, and she is heading straight for Tempest.
